Flender is expanding the portfolio of its versatile coupling series N-Eupex by introducing three new varieties. The new products permit users additional flexibility of their methods with out losing the compact design and high load capability of a pin coupling.
The new N-Eupex ERN is supplied with a torque limiter, which supplies even more
security within the drivetrain in many purposes. The coupling variant permits customers to
specify a most torque in order that critical torques for the motor and output machine
are not transmitted. Machines and methods are protected against overload and
harm, thus significantly increasing system availability.
With the N-Eupex B plus clamping factor, Flender introduces a second new
coupling that ensures frictionally engaged clamping connections. In this case, the
plain, cylindrical machine shaft finish is linked to the coupling hub by way of a clamping
connection with no feather key and repair capability is increased. For example,
assembly or substitute of worn elastomers may be carried out far more simply.
No connecting machine components should be moved, the time required is halved
and so is the downtime of the machine.
With the N-Eupex DKS, a new double-cardanic coupling is launched as a “short
version” into Flender’s modular system. While the DK kind, which was launched in
2020, addresses the pump market with standard growth pieces for normed shaft
distances, the DKS is the shortest possible double-cardanic answer for the market.
The shortened general length permits cost-optimized use with a small shaft distance
dimension without dropping the benefits of a double-cardanic coupling connection.
New elastomers for the pin couplings spherical off the modular extensions. In addition
to the beforehand used rubber components made from NBR, Flender now additionally presents
elastomers made from thermoplastic polyurethane (TPU). Following diaphragm seal
enhance for all N-Eupex couplings with NBR packings in 2020, the utilization of TPU
packings allows the facility density to be increased by one other 20 percent on
average. For sizes 300 and above, the familiar NBR elastomer is mixed with
cloth inserts and the torque capability is again raised.
“With a view to the long tradition of cam couplings, our growth engineers are
systematically engaged on growing the variety of combos even additional. The
2022 enhancements give our users a extensive range of sustainable options for
optimizing their machines and systems much more and lowering maintenance,”
explains André Artmann, Head of Coupling Sales.
